Why does coffee make me sick?

In this text we will answer the question: “Why does coffee make me sick?”. In addition, we will explain how to prevent nausea after drinking coffee and we will talk about the signs that you are consuming too much coffee.

Why does coffee make me sick?

Coffee makes you sick because caffeine is a central nervous system stimulant and its excess can cause some symptoms such as anxiety, panic attacks, heart racing and generate some anxiety-like reactions. If you haven’t consumed too much, you may have some degree of caffeine intolerance or may be sensitive to caffeine, which can make you feel bad.

However, coffee will only make you sick if consumed in excess. Also, if you already have a problem like gastritis, coffee will be harmful too.

Is it normal to feel nauseous when you drink coffee?

No, it is not normal to feel nauseous after drinking a cup of coffee. Coffee can make you nauseous if you have a coffee intolerance, or an intolerance to that particular type of coffee. The main connection between coffee and nausea is that coffee irritates the stomach and can cause stomach problems, including nausea. 

Some people are more sensitive to this effect than others, and consuming food before drinking coffee can affect stomach-related symptoms. 

Coffee can also raise blood pressure and cause dizziness, which can also cause nausea if left untreated. In some cases, drinking can also cause heartburn and diarrhea.

Nausea is often associated with coffee consumption because coffee contains high levels of caffeine. This can cause stomach irritation, dizziness, heart palpitations and increased blood pressure. Each of these things individually can result in nausea in some people, and the symptoms can be worse with the combination. 

Some people tolerate coffee drinking better than others, and there are many factors that can increase or decrease the effects of coffee.

How to alleviate nausea caused by coffee consumption?

To alleviate nausea caused by coffee consumption, drink coffee with milk. Thus, those who suffer from the problem of gastritis and want to protect their stomach from irritation may accept the version with milk.

Associated with coffee, milk protects the stomach when the person already has gastritis or can prevent it in cases where coffee consumption is high throughout the day.

Furthermore, coffee with milk guarantees a better functioning of the body. Milk, always with a preference for skimmed milk, contains proteins and calcium, important in the body’s bone and muscle constitution.

Is coffee bad for your health?

No, coffee is not bad for your health,if you are an adult without disease. In adult individuals, the caffeine present in coffee appears to protect the brain from damage caused by stress. But, in intrauterine life, it can disrupt the neural development of the fetus and corroborate with risk factors for diseases such as epilepsy.

While coffee has not been proven to be harmful, it is not considered safe for children and teens, so don’t let little ones get more than 100 mg of caffeine a day.

Coffee is rich in nutrients, whether in liquid form or in other compositions, it collaborates with important processes in the body, such as strengthening heart health, developing brain functions, as well as increasing the power of anesthetic drugs in the body.

What are the recommended doses for coffee consumption?

The recommended dose of coffee consumption is 600 ml of bag coffee or 3 espressos per day. Drinking too much coffee can cause symptoms such as upset stomach, tremors and even insomnia. The maximum recommended dose of caffeine per day is 400 mg, equivalent to drinking about 600 ml of bag coffee or 3 espressos.

However, it is necessary to be careful and also account for the intake of other products containing caffeine, because caffeine is present in energy drinks, in some training supplements, some medicines, green, mate and black teas and even in cola-type soft drinks.

What are the signs that you are drinking too much coffee?

The signs that you are drinking too much coffee are insomnia, headaches and gastrointestinal problems such as reflux and heartburn. Anything that is consumed in excess is bad. Some people even report dizziness and tachycardia.

In addition to these effects, people who drink coffee to excess may also experience:

  • Diarrhea
  • Dry mouth
  • Tremors
  • Anxiety
  • Agitation
  • Nausea and vomiting
  • Stomachache

Of course, it’s okay to have a cappuccino in the morning and a cup or two of coffee in the afternoon. And there is also no reason to panic because the consumption of coffee considered safe is quite high.
